Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically a steel bar welding positioning device. Background Technology

[0002] A rebar welding positioning device is an auxiliary tool used to accurately fix the position of rebars and ensure welding quality. It typically consists of clamps, positioning slots, and a fixing bracket. Its core function is to quickly align rebar joints through mechanical structures or magnetic adsorption, maintaining stable welding spacing and angles, avoiding manual placement deviations, and significantly improving welding efficiency and joint strength consistency. The device is mostly made of high-temperature resistant steel, and some designs integrate protective baffles to prevent weld spatter. It is suitable for welding rebar mesh and skeletons in precast component processing or on-site construction, and is particularly beneficial for ensuring process standardization during batch operations.

[0003] In the prior art, patent application number 202321808298.X, entitled "A Longitudinal Reinforcing Bar Welding Positioning Device for a Cylindrical Reinforcing Bar Cage," is disclosed. The device includes a base plate with symmetrical longitudinal positioning structures on both sides of its upper surface. Each longitudinal positioning structure includes a first outer shell, the lower surface of which is fixedly connected to the upper surface of the base plate. A connecting rod is movably connected to clamping plates via a pin. Two clamping plates pass through the first outer shell and are slidably connected to slide rails machined on it. Through the cooperation of the positioning structure and the base plate, a first motor is started, driving a lead screw to rotate. The rotation of the lead screw causes a threaded seat to rotate upwards on a first limiting rod, simultaneously moving a crossbar upwards and simultaneously moving two second limiting rods on both sides to slide rails machined within the first outer shell. The upward sliding mechanism clamps and positions the reinforcing bars, avoiding the need for manual rotation of the fixing components. This prevents damage to the bars due to worker error and avoids impacting subsequent production processes. However, its reinforcing bar fixing structure is relatively simple, using only two non-adjustable semi-circular clamps. This fixing method has significant limitations: the clamps have limited fixing effectiveness and cannot stably fix reinforcing bars of different specifications during processing. Furthermore, due to its lack of adjustability, it cannot precisely adjust the position of the reinforcing bars in horizontal, vertical, and angular directions, and it is also difficult to achieve rotation and precise positioning of the reinforcing bars, resulting in poor welding effects. Therefore, a new technical solution is needed to address these issues. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to again Figure 1-4This utility model provides a rebar welding positioning device, including an operating table 100. Two longitudinal adjustment frames 110 are fixedly connected to the top of the operating table 100. A first motor 111 is fixedly connected to the top of each longitudinal adjustment frame 110. The bottom end of the power output shaft of the first motor 111 passes through the longitudinal adjustment frame 110 and extends into the inner cavity of the longitudinal adjustment frame 110. A first threaded rod 112 is fixedly connected to the bottom end of the power output shaft of the first motor 111. A mounting frame 120 is fixedly connected between the inner sides of the two longitudinal adjustment frames 110. A welding rod is fixedly connected to the bottom of the mounting frame 120. The connector 121 has a mounting base 130 screwed onto the outer side of the first threaded rod 112. A second motor 131 is fixedly connected to one side of the mounting base 130. One end of the power output shaft of the second motor 131 is fixedly connected to a transverse adjustment chamber 140. A third motor 141 is fixedly connected to one side of the transverse adjustment chamber 140. One end of the power output shaft of the third motor 141 passes through the transverse adjustment chamber 140 and extends into the inner cavity of the transverse adjustment chamber 140. A second threaded rod 142 is fixedly connected to one end of the power output shaft of the third motor 141. The second threaded rod 142 is screwed onto the fixing base 200.

[0022] Specifically, by operating the control mechanism on the operating table 100, the third motor 141 is started to drive the second threaded rod 142 to a designated position, causing the fixed seat 200 installed on the second threaded rod 142 to move. The distance between the two fixed seats 200 is adjusted so that the fixing mechanism on the fixed seat 200 can fix steel bars of different lengths. Then, the first motor 111 is started to drive the first threaded rod 112 to rotate, causing the steel bar fixed by the fixing mechanism to move to the designated position. After that, the welder 121 is started to weld the steel bar. During the welding process, the second motor 131 is started to drive the transverse adjustment chamber 140 to rotate, improving the welding effect of the welder 121 on the steel bar.

[0023] Example 2: Please refer to again Figure 1-4 A fixed base 200 is provided above the operating table 100. Adjusting rods 210 are fixedly connected to both sides of the inner cavity wall of the fixed base 200. One end of the adjusting rod 210 is fixedly connected to the mounting plate 220. A clamping protrusion 230 is fixedly connected to one side of the mounting plate 220. Anti-slip grooves 231 are provided on the outer side of the clamping protrusion 230, and the anti-slip grooves 231 are arranged in sequence. A fourth motor 240 is fixedly connected to the top of the mounting plate 220. The bottom end of the power output shaft of the fourth motor 240 passes through the mounting plate 220 and extends into the inner cavity of the mounting plate 220. A third threaded rod 241 is fixedly connected to the bottom end of the power output shaft of the fourth motor 240. A clamping recess 250 is screwed to the outer side of the third threaded rod 241. The clamping recess 250 is located above the clamping protrusion 230.

[0024] Specifically, when fixing the reinforcing bar, the reinforcing bar is placed between the two reinforcing bar mechanisms. Then, the adjusting rod 210 is extended, causing the adjusting rod 210 to move the two fixing mechanisms closer together, so that the clamping protrusions 230 in the two fixing mechanisms come into contact with the reinforcing bar. Then, the fourth motor 240 is started to drive the third threaded rod 241 to rotate, causing the clamping concave block 250 installed on the third threaded rod 241 to move downward, so that the clamping concave block 250 cooperates with the clamping protrusion 230 to form a V-shaped clamping angle, thus firmly fixing the reinforcing bar.

[0025] Working principle: When fixing the reinforcing bar, the reinforcing bar is placed between the two reinforcing bar mechanisms. Then, by activating the adjusting rod 210, it extends, causing the two fixing mechanisms to move closer together. This brings the clamping protrusions 230 in the two fixing mechanisms into contact with the reinforcing bar. Then, by activating the fourth motor 240, the third threaded rod 241 rotates, causing the clamping recess 250 mounted on the third threaded rod 241 to move downwards. This allows the clamping recess 250 to cooperate with the clamping protrusions 230 to form a V-shaped clamping angle, thus firmly fixing the reinforcing bar. The third motor 240 is activated via the control mechanism on the operating table 100. Motor 141 drives the second threaded rod 142 to a specified position, causing the fixed seat 200 mounted on the second threaded rod 142 to move and adjust the distance between the two fixed seats 200 so that the fixing mechanism on the fixed seat 200 can fix steel bars of different lengths. Then, the first motor 111 is started to drive the first threaded rod 112 to rotate, causing the steel bar fixed by the fixing mechanism to move to the specified position. After that, the welder 121 is started to weld the steel bar. During the welding process, the second motor 131 is started to drive the transverse adjustment chamber 140 to rotate, improving the welding effect of the welder 121 on the steel bar.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
